Good stability when assembled, preventing the bounce-back effect
Sealing for low and high viscosity fluids
Modern primary sealing lip with low radial forces

TransmissionSpeed
The table below indicates the relationships between the linear speed, the rotation speed and the recommended material.The shaft seals with an additional protective lip are limited to a speed of 8 m/s.Linear speed calculation:s (m/s) = [Ø shaft (mm) x speed (rpm) x π] / 60,000Pressure
The standard shaft seals are generally used in unpressurised environments, or for pressures between 0.02 and 0.05 MPa maximum.Higher pressures are acceptable, following testing, for standard NBR or FKM shaft seals used on a shaft diameter less than 30 mm. Refer to the graph below:Temperature

Fluids
Mineral oils
In general, this type of oil has few additives and is therefore perfectly suitable for all of the rubbers used for the rotary shaft seals. The following oils are suitable for rotating applications:- motor oils
- gearbox oils
- hypoid oils
- ATF oils for automatic gearboxes
- transmission oils
synthetic oils
This type of oil is used to improve different characteristics such as the resistance to ageing, resistance to high temperatures, viscosity, etc. and has a good compatibility with the majority of rubbers used for the shaft seals. Tests may need to be performed beforehand to measure the degree of compatibility of this type of oil with the materials used. Among the synthetic oils are:- brake fluids
- fluids for automatic gearboxes
- fluids for suspensions
- fluids for steering systems
- fluids for hydraulic transmissions
Hypoid oils
This type of oil contains special components such as EP additives. These enable lubrication and thus limit any seizing at the bearings, for example. When affected by heat, these additives have the tendency to lead to deposits on the sealing lip. That is why we recommend using shaft seals with a sealing lip comprising return pumping leads in order to limit the increase in temperature and above all, to reduce these potential carbon deposits.Greases
Greases are generally applied to bearings etc. and require specific adaptation to provide favourable operating conditions for the shaft seal. To prevent the lip of the seal from sustaining more significant pressures than planned, we recommend positioning the lip seal on one side of the bearing in such a way so that the lip is not prematurely destroyed. We also recommend reducing the rotation speed by 50% when lubricated, to ensure that less heat escapes during friction.Aggressive fluids
It is critical to choose the correct material to better resist different aggressive fluids (acids, solvents, chemical products, etc.). For applications in a rotating environment, we recommend using materials such as FKM rather than NBR. For operations that are dry or use very little lubrication, and where the rubbers do not resist certain aggressive fluids, we advise you to use our PTFE shaft seals.SEAL DESIGN
Tolerance for the outside diameter of the seal (ØD)
The table below indicates the pre-tightening for shaft seals on the housing diameter according to standard ISO 6194-1.Bore diameter ØD1 (mm) | Tolerances on the outside diameter ØD of the ring | Roundness tolerance |

Tolerance for the inside diameter of the seal (Ød)
Free and without constraint, the inside diameter of the sealing lip is always smaller than the diameter of the shaft. The pre-tightening or interference denotes the difference between these two values. Depending on the shaft diameter, the diameter of the sealing lip is generally considered to be less, between 0.8 and 3.5 mm.SHAFT DESIGN
Shaft materialSuitable materials are:- ordinary C35 and C45 steels used in mechanical construction
- 1.4300 and 1.4112 stainless steels for sealing water
- sprayed carbide coatings
- graphite
- malleable cast iron
- materials with a CVD and PVD coating
Not appropriate:- chrome coatings solidified through non-uniform wear
- plastic materials resulting from low thermal conductivity, which can lead to a disturbance in the transport of heat, an increase in temperature in friction areas with the shaft seal, as well as a potential softening
Shaft hardnessShaft hardness will depend on the linear speed (in m/s) and the level of pollution.Rotation speed | Hardness in HRC |

s ≤ 4.0 m/s | 45 HRC |
4.0 < s ≤ 10.0 m/s | 55 HRC |
